' TREE-TELLING Eoor oAm).

To all whom zit may concern:

Be it known that I, PERRY GRAHAM, a citizen of the United States, residing at Blaine, in the county of lVhatcom and State of Washington have invented a new and useful Tree-Felling F ootboard, of which the following is a specification) Thisinvention relates to improvements in tree felling footboards.

An object of the present invention is to provide a device ofthe class named which may be easily and quickly secured to a tree and in which the supporting board may be moved to any angle throughout a large are.

A further object is to provide a tree felling device which is adapted to wedgedly engage the trunk of a tree or other struc tures and includes a stay rod which fastens to the structure at a distance above the wedge engagement of the device and necessarily holds the same in place and to which is pivotally secured a footboard for the support of the ax men.

With the foregoingand other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawing accompanying this specification and forming a part thereof, the preferred embodiment of my invention is illustrated, in which z Figure 1 is a View in perspective of my improved device showing the same attached to the trunk of a tree. Fig. 2 is. a vertical sectional view thereof. Fig. 3 is a detail view in perspective of the supporting board" proper. Fig. 4 is a view of-a somewhat mod ified form of stay rod to be used in connection with my improved device. Fig. 5 is a cross sectlonal view taken on the line 55 1 of Fig. 2.

i is a supporting bracket 7. The supporting bracket has a central portion 8 removed for a purpose which will be more fully heresents a.:.-broad fflat outer' surface against Thedevice herein disclosed may be used for felling treesor may be used with equal facility upon poles bridge structures and the like. The block or head 6 is provided with an aperture 10 which as illustrated in Fig. 2 lies above the central opening 8 of the supporting bracket. or platform 11 is providedat its end with a bracket 12 secured thereto and which bracket is provided with an upstanding pin 3 13 which as illustrated inFig. 1 is adapted to project within the opening 10.

The supporting board rests upon the A supporting board Specification of Letters latent. Patented Sept; 8 1914. Application filedflrebruary 2, 1914. Serial No. 816,074.

which are directed the blows for the'securing of the wedge I to a tree or :allied structure 9.

bracket 7 .and as weight is brought to bear upon the outer extremity of the platform 11, the end is moved upward within the opening 10 and the friction accompanying such force of contact prevents the accidental displacement or swinging of the supporting board. In orderto positively prevent the accidental displacement or swinging ofthe supporting'board the supporting bracket 7 is serrated and the bracket 12 is also -ser I rated as illustrated in Fig. 5. However'it is to be noted that the board may be moved about the pivot or pin 13 asa center to thus.

vary the angularadjustment of the supporting board to suit the bearing conditions as the tree is being cut. or felled.

A staple or equivalent 14 is carried by the upper portion of the block or head 6 and to which is hingedlyv secured a stay rod 15. The upper extremity of the stay rod is bent inward and provided with the sharpened blade 16 adapted to be forcibly'driven into the structure 9 as illustrated in Fig.2. A somewhat modified form of stay rod is illustrated. in Fig. 4; in which the dog hook 16 is pivotally secured to the upper extremity 17 of the stay rod and takes the place of the ordinary blade 16. The stay rod extendsat anangle to the trunk of the tree and thus thought will be readily appreciated from a reference to the drawings. When it is desiredto remove the supporting board from the block it may be accomplished by raising the outer extremity of the board which low securely anchors the wedge in place as [it is foregoing is rendered possible by providing the central openings 8 in the supporting bracket.

Having thus fully described my invention, what I claim as new is A device of the class described conipristhe aperture of the supporting bracket, and

a platform provided with an upstanding pivot resting upon said supporting bracket with the pivot removably projecting within the head opening.

In testimony that I claim the foregoing as my own, I have hereto aifixed my signature in the presence of two witnesses.
